Definitions
- the present invention relates to a device and a method for coating plates, in particular a coating system with flowable coating material for structured surfaces.
- the DE 20 2004 018 710 U1 shows a device for coating arranged on a conveyor belt plates, which are then fed to individual coating stations.
- a coating station if necessary, after a primer, paint is applied to a plate via an applicator roll.
- the applicator roll can be profiled for introducing an embossed structure.
- the lacquer is then cured, for example with UV radiation, so that two separate stations are present, wherein after profiling the surface of the coating can still change.
- the structure by inserting a release layer is relatively complicated, and also after a certain period of time, the structured film must be replaced, which is relatively expensive.
- aligning the profiling of the film to an underlying decorative image is difficult because of the stretchability of the film.
- At least one radiation source for simultaneous profiling and curing of the coating material is provided in the region of the at least one roller.
- the coating material can be profiled and cured without the use of a structured film, so that a structurally simple structure is present and also eliminates the change of a structured film.
- the coating material is cured under exclusion of air in the region of the roller, so that a particularly accurate profiling of the coating material is possible, with a spatial agreement of the embossing and located under the coating material on the plate print image can be achieved.
- a radiation source curing can also be done comparatively quickly, so that the system can be operated at high speeds.
- Profiling is understood to mean the introduction of a structure into a surface, the terms “profiling” and “embossing” being used interchangeably.
- an “embossing” of the coating material is intended to mean the introduction of a desired surface structure with elevations and depressions, which preferably between 10 .mu.m and 1 mm, in particular in a range between 0.1 mm and 0.8 mm.
- curing of the coating material may be a partial (hardening) or complete curing.
- the roller for the radiation of the radiation source is formed substantially permeable, which can be used as a radiation source UV rays or electron beams.
- the roller may be made of transparent material, preferably glass or plastic, although several materials may be used.
- the radiation source can be arranged both above the roller on the opposite side to the plate and in the roller, wherein the arrangement in the roller has the advantage that radiation losses are comparatively small.
- baffles are preferably provided adjacent to the roller in order to delimit the effective range of the radiation source.
- these baffles are provided at least on the input side of the roller.
- the baffles can be adjustable in order to adjust the effective range of the radiation source can.
- a method is also provided in which the coating material in the area of the roll can be profiled and cured simultaneously in order to obtain the advantages according to the invention.
- the plate printed with a pattern prior to coating is controlled synchronously with the profiled roller, so that the embossing of the coating material is matched to the pattern.
- certain points or marks on the decorative image can be detected and forwarded to a controller, which then controls the profiled roller so that a certain embossing section of the roller impinges on the dot or the marker.
- a sealable coating material 11 is applied to a plate 10 in a coating station.
- the thus coated plate 10 with the coating material 11 is conveyed to a station for curing and profiling on a conveyor belt 30 which is driven by a drive roller 31 and guided over guide rollers 32.
- a calender-shaped roller 20 is provided, which is profiled on its outer side, for example in order to impress pores in the coating material.
- the roll 20 with the embossed structure is pressed onto the still liquid coating material 11 so that a coating structure is transferred. If it is provided that the embossing pattern is exactly matched to an image or pattern previously printed on the plate, the roller and the plate transport are precisely matched via optical recognition and electronic control.
- the coating material 11 is irradiated by a radiation source 21, so that jets 22 impinge on the coating material 11.
- the roller 20 is made of a radiolucent material, for example of certain types of glass or transparent plastic.
- the radiation source 21 can generate rays 22 as UV radiation or also electron radiation.
- the generated radiation must be matched to the chemical composition of the coating material 11, wherein the coating material 11 may be formed as UV or electron beam curable lacquer.
- the Rays 22 of the radiation source 21 impinge on the coating material in the area of the roller 20.
- a guide plate 23 is further provided to limit the effective range of the radiation source 21.
- the coating material 11 is cured exclusively with exclusion of air, since during curing the roll surface rests on the coating material 11.
- the baffles 23 is avoided that the coating material 11 before the direct contact of the roller 20 on the coating material 11 hardens. Curing and curing under exclusion of air can positively influence the surface quality.
- a radiation source 41 is not disposed within the one roller 40 having an outer embossing structure on the circumference, but the roller 40 is formed as a hollow roller.
- the beams 42 of the radiation source 41 can impinge on the coating material 11 through the roller 40, wherein a particularly precise alignment of the beams 42 is possible by adjacently arranged guide plates 43.
- radiation losses can be kept low because the beams 42 only have to pass through a wall of the roller 40.
- a surface structure of the coating material 11 can be particularly well aligned with an underlying decorative image, which consists for example of a wood grain, tiles or other images.
- the embossing of the roller 20 with the embossed structure can be aligned so that the embossed structure of a wood grain fits exactly to the underlying decor image.

Description
Die vorliegende Erfindung betrifft eine Vorrichtung und ein Verfahren zum Beschichten von Platten, insbesondere eine Beschichtungsanlage mit fließfähigem Beschichtungsmaterial für strukturierte Oberflächen.The present invention relates to a device and a method for coating plates, in particular a coating system with flowable coating material for structured surfaces.
Die
Aus der noch nicht veröffentlichten Anmeldung PCT /
Bei einer solchen Beschichtungsanlage ist der Aufbau durch Einfügen einer Trennschicht relativ kompliziert, wobei zudem nach einer gewissen Zeitdauer die strukturierte Folie ausgewechselt werden muss, was vergleichsweise aufwendig ist. Zudem ist das Ausrichten der Profilierung der Folie auf ein darunter liegendes Dekorbild wegen der Dehnbarkeit der Folie schwierig.In such a coating system, the structure by inserting a release layer is relatively complicated, and also after a certain period of time, the structured film must be replaced, which is relatively expensive. In addition, aligning the profiling of the film to an underlying decorative image is difficult because of the stretchability of the film.
Es ist daher Aufgabe der vorliegenden Erfindung eine Vorrichtung und ein Verfahren zum Beschichten von Platten zu schaffen, mittels dem das Beschichtungsmaterial bei einfachem Aufbau der Anlage exakt profiliert bzw. geprägt werden kann.It is therefore an object of the present invention to provide a device and a method for coating plates, by means of which the coating material can be accurately profiled or embossed with a simple structure of the system.
Diese Aufgabe wird mit einer Vorrichtung mit den Merkmalen des Anspruches 1 sowie einem Verfahren mit den Merkmalen des Anspruches 9 gelöst.This object is achieved with a device having the features of claim 1 and a method with the features of claim 9.
Erfindungsgemäß ist im Bereich der mindestens einen Walze mindestens eine Strahlungsquelle zum gleichzeitigen Profilieren und Härten des Beschichtungsmaterials vorgesehen. Dadurch kann das Beschichtungsmaterial ohne die Verwendung einer strukturierten Folie profiliert und ausgehärtet werden, so dass ein konstruktiv einfacher Aufbau vorhanden ist und zudem das Wechseln einer strukturierten Folie entfällt. Das Beschichtungsmaterial wird dabei unter Luftabschluss im Bereich der Walze ausgehärtet, so dass ein besonders exaktes Profilieren des Beschichtungsmaterials möglich ist, wobei eine räumliche Übereinstimung der Prägung und einem unter der Beschichtungsmaterial auf der Platte befindlichen Druckbild erreicht werden kann. Durch den Einsatz einer Strahlungsquelle kann das Aushärten auch vergleichsweise schnell erfolgen, so dass die Anlage mit hohen Geschwindigkeiten betrieben werden kann.According to the invention, at least one radiation source for simultaneous profiling and curing of the coating material is provided in the region of the at least one roller. Thereby, the coating material can be profiled and cured without the use of a structured film, so that a structurally simple structure is present and also eliminates the change of a structured film. The coating material is cured under exclusion of air in the region of the roller, so that a particularly accurate profiling of the coating material is possible, with a spatial agreement of the embossing and located under the coating material on the plate print image can be achieved. By using a radiation source curing can also be done comparatively quickly, so that the system can be operated at high speeds.
Unter Profilieren wird das Einbringen einer Struktur in eine Oberfläche verstanden, wobei die Begriffe "Profilieren" und "Prägen" synonym verwendet werden. Dabei soll ein "Prägen" des Beschichtungsmaterials das Einbringen einer gewünschten Oberflächenstruktur mit Erhöhungen und Vertiefungen bedeuten, die vorzugsweise zwischen 10µm und 1mm, insbesondere in einem Bereich zwischen 0,1mm und 0,8mm liegen.Profiling is understood to mean the introduction of a structure into a surface, the terms "profiling" and "embossing" being used interchangeably. In this case, an "embossing" of the coating material is intended to mean the introduction of a desired surface structure with elevations and depressions, which preferably between 10 .mu.m and 1 mm, in particular in a range between 0.1 mm and 0.8 mm.
Soweit in der Anmeldung von "Aushärten" des Beschichtungsmaterials gesprochen wird, kann es sich um ein teilweises (Anhärten) oder vollständiges Aushärten handeln.As far as in the application of "curing" of the coating material is spoken, it may be a partial (hardening) or complete curing.
Vorzugsweise ist die Walze für die Strahlen der Strahlungsquelle im wesentlichen durchlässig ausgebildet, wobei als Strahlungsquelle UV-Strahlen oder Elektronstrahlen eingesetzt werden können. Die Walze kann aus transparentem Material, vorzugsweise Glas oder Kunststoff hergestellt sein, wobei auch mehrere Werkstoffe zum Einsatz kommen können. Die Strahlungsquelle kann dabei sowohl oberhalb der Walze auf der zur Platte gegenüberliegenden Seite als auch in der Walze angeordnet sein, wobei die Anordnung in der Walze den Vorteil hat, dass Strahlungsverluste vergleichsweise gering sind.Preferably, the roller for the radiation of the radiation source is formed substantially permeable, which can be used as a radiation source UV rays or electron beams. The roller may be made of transparent material, preferably glass or plastic, although several materials may be used. The radiation source can be arranged both above the roller on the opposite side to the plate and in the roller, wherein the arrangement in the roller has the advantage that radiation losses are comparatively small.
Um das An- oder Aushärten besonders exakt in einem vorgegebenen Bereich ausführen zu können, sind benachbart zu der Walze vorzugsweise Leitbleche vorgesehen, um den Wirkbereich der Strahlungsquelle einzugrenzen. Vorzugsweise sind diese Leitbleche zumindest auf der Eingangsseite der Walze vorgesehen. Die Leitbleche können dabei verstellbar sein, um den Wirkbereich der Strahlungsquelle anpassen zu können.In order to be able to carry out the curing or hardening particularly precisely in a predetermined region, baffles are preferably provided adjacent to the roller in order to delimit the effective range of the radiation source. Preferably, these baffles are provided at least on the input side of the roller. The baffles can be adjustable in order to adjust the effective range of the radiation source can.
Erfindungsgemäß wird auch ein Verfahren bereitgestellt, bei dem das Beschichtungsmaterial im Bereich der Walze gleichzeitig profiliert und ausgehärtet werden kann, um zu den erfindungsgemäßen Vorteilen zu gelangen.According to the invention, a method is also provided in which the coating material in the area of the roll can be profiled and cured simultaneously in order to obtain the advantages according to the invention.
Gemäß einer bevorzugten Ausgestaltung der Erfindung wird mittels optischer Erkennungsmittel, insbesondere Kameras, die vor der Beschichtung mit einem Muster bedruckte Platte synchron zu der profilierten Walze gesteuert, so dass die Prägung des Beschichtungsmaterials auf das Muster abgestimmt wird. Hierfür können bestimmte Punkte oder Markierungen an dem Dekorbild erfasst und an eine Steuerung weitergeleitet werden, die dann die profilierte Walze so steuert, dass ein bestimmter Prägeabschnitt der Walze auf den Punkt oder die Markierung auftrifft.According to a preferred embodiment of the invention, by means of optical detection means, in particular cameras, the plate printed with a pattern prior to coating is controlled synchronously with the profiled roller, so that the embossing of the coating material is matched to the pattern. For this purpose, certain points or marks on the decorative image can be detected and forwarded to a controller, which then controls the profiled roller so that a certain embossing section of the roller impinges on the dot or the marker.
Die Erfindung wird nachfolgend anhand zweier Ausführungsbeispiele mit Bezug auf die beigefügten Zeichnungen näher erläutert. Es zeigen:
- Figur 1
- eine schematische Ansicht einer Vorrichtung zum beschichten einer Platte gemäss einem ersten Ausführungsbeispiel, und
- Figur 2
- eine schematische Ansicht einer Vorrichtung zum Beschichten einer Platte nach einer zweiten Ausführungsform.
- FIG. 1
- a schematic view of an apparatus for coating a plate according to a first embodiment, and
- FIG. 2
- a schematic view of an apparatus for coating a plate according to a second embodiment.
Bei der in Figur 1 gezeigten Ausführungsform wird ein schließfähiges Beschichtungsmaterial 11 auf eine Platte 10 in einer Beschichtungsstation aufgetragen. Die so beschichtete Platte 10 mit dem Beschichtungsmaterial 11 wird zu einer Station zum Aushärten und Profilieren über ein Transportband 30 gefördert, das über eine Antriebsrolle 31 angetrieben und über Umlenkrollen 32 geführt ist.In the embodiment shown in Figure 1, a
Zum Profilieren des Beschichtungsmaterials 11 ist eine als Kalander ausgebildete Walze 20 vorgesehen, die an ihrer Außenseite profiliert ist, beispielsweise um Poren in das Beschichtungsmaterial einzuprägen. Die Walze 20 mit der Prägestruktur wird auf das noch flüssige Beschichtungsmaterial 11 gedrückt, so dass eine Beschichtungsstruktur übertragen wird. Falls vorgesehen ist, die Prägestruktur exakt auf ein bereits vorher auf die Platte gedrucktes Bild oder Muster abzustimmen, wird die Walze und der Plattentransport über eine optische Erkennung und eine elektronische Steuerung genau aufeinander abgestimmt. Während der Übertragung der Beschichtungsstruktur in das Beschichtungsmaterial 11 durch die Walze 20 wird das Beschichtungsmaterial 11 durch eine Strahlenquelle 21 bestrahlt, so dass Strahlen 22 auf das Beschichtungsmaterial 11 auftreffen.For profiling the
Daher ist die Walze 20 aus einem strahlendurchlässigen Material, beispielsweise aus bestimmten Glassorten oder aus transparentem Kunststoff hergestellt. Die Strahlenquelle 21 kann Strahlen 22 als UV-Strahlung oder auch Elektronenstrahlung erzeugen. Die erzeugte Strahlung muss auf die chemische Zusammensetzung des Beschichtungsmaterials 11 abgestimmt sein, wobei das Beschichtungsmaterial 11 als UV- oder Elektronenstrahl- härtbarer Lack ausgebildet sein kann. Die Strahlen 22 der Strahlenquelle 21 treffen dabei im Bereich der Walze 20 auf das Beschichtungsmaterial auf.Therefore, the
Auf der Einlaufseite der Walze 20 ist ferner ein Leitblech 23 vorgesehen, um den Wirkbereich der Strahlungsquelle 21 einzugrenzen. Dadurch wird erreicht, dass das Beschichtungsmaterial 11 ausschließlich unter Luftabschluss ausgehärtet wird, da während des Aushärtens die Walzenoberfläche auf dem Beschichtungsmaterial 11 aufliegt. Durch die Leitbleche 23 wird vermieden, dass das Beschichtungsmaterial 11 vor dem direkten Aufliegen der Walze 20 auf dem Beschichtungsmaterial 11 vorhärtet. Die An- und Aushärtung unter Luftabschluss kann die Oberflächenqualität positiv beeinflussen.On the inlet side of the
Bei dem in Figur 2 gezeigten zweiten Ausführungsbeispiel ist eine Strahlungsquelle 41 nicht innerhalb der einen Walze 40 mit einer äußeren Prägestruktur am Umfang angeordnet, sondern ist die Walze 40 als Hohlwalze ausgebildet. Dadurch können die Strahlen 42 der Strahlungsquelle 41 durch die Walze 40 auf das Beschichtungsmaterial 11 auftreffen, wobei durch benachbart angeordnete Leitbleche 43 eine besonders genaue Ausrichtung der Strahlen 42 möglich ist. Zudem können Strahlungsverluste gering gehalten werden, da die Strahlen 42 nur durch eine Wand der Walze 40 hindurchtreten müssen.In the second embodiment shown in Figure 2, a
Bei den beiden Ausführungsbeispielen lässt sich eine Oberflächenstruktur des Beschichtungsmaterials 11 besonders gut auf ein darunter liegendes Dekorbild ausrichten, das beispielsweise aus einer Holzmaserung, Fliesen oder anderen Bildern besteht. Die Prägung der Walze 20 mit der Prägestruktur kann dabei so ausgerichtet sein, dass die Prägestruktur einer Holzmaserung exakt zu dem darunter liegenden Dekorbild passt.In the two exemplary embodiments, a surface structure of the
